I Application filed June 12. 1907- Serial No. 378.589.

To all whom it may concern: I

Be it known that 1, CHARLES S. ERGEN- BRIGHT, a citizen of the UnitedStates, residing at Caney, in the county of Montgom cry and State ofKansas, have invented certain new and useful Improvements in Hand-Plows, of which the following is a specification.

This invention pertains to a new and useful hand-disk-plow, and theobjectthereof is to provide a device of this character, which is simpleand efficient in construction, and comparatively easy to operate.

The invention aims, as a further object, to provide a device, havingthedisks adjustably connected with rearwardly extending arms, of a U-sha edportion, which is supported by suitable wieels, as clearly shown in theac companying drawings.

This invention comprises further objects and combinations of elementswhich will be hereinafter more fully described, shown in theaccompanying drawings, and the novel features thereof will be pointedout in the appended claims. v

To obtain a full and correct understanding of the details ofconstruction, combinations of features, elements and advantages,reference is to be had to the hereinafter set forth description and theaccompanying drawings in connection therewith, wherein,

Figure 1 is a perspective view of the plow, illustrating the principalfeatures thereof. Fig. 2 is a sectional view through the fourway jointmember, and the connection of the disks, with the rearwardly extendingarms. Fig. 3 is a detail perspective view of the fourway joint memberdetached. Fig. 4 is a sectional view of the disks, their axle and theiradjustable connection. Fig. 5 is a detail viewsimilar to Fig. 4, showing3 disks combined.

Making renewed reference to the accompanying drawings, wherein similarreference characters indicate corresponding parts in the severalillustrations, by figure, 1 designates wheels, which are mounted onstubaxles 2, which are journaled in bearings 3 of the four-way jointmembers 4 and 5, as clearly shown. These joint members are provided witha vertically disposed bore 6,

which receive the side arms 7 and 8, of the U-shaped member9, as clearlyshown. Below these bores, the said arms of the U- shaped member are bentat right angles thereto, as at 10, and then they are shaped into acompound curve, as at 11, and then the members formed by the compoundcurves receive at their extreme end a socket member 12, which is securedthereto by thumb screws.

Extending through the socket members and at right angles "thereto, arevertically disposed shafts 14, which are held adjustably therein, bythumb screws 15. Each one of the shafts 14, is provided with a T-joint16 through which the axles of the disks pass: Each axle is held in itsbearing, that is, adjustably, by a thumb screw 17, as clearly shown.Each four-way joint member has extending rearwardly therefrom, arms 18which connect as at 19, to a bar 20, which is provided with a cross barforming a handle 21 for the plow, as clearly illustrated in thedrawings.

As shown in Fig. 4, the disks 27 are connected by an axle 24*.

In the modification shown in Fig. 5, the combination of three disks aremounted on two axles 23 and 24, which are connected together by thescrew-threaded projection 26 which engages the screwthreaded portion 25,as clearly shown.

It is to be understood that various changes and modifications may beemployed in the construction and embodiment thereof, combinations offeatures and elements without in any way departing from the spirit andscope of the invention covered by the claims thereof: it beingunderstood that whatever variations or modifications are employed mustfall within the scope of the appended claims.

From the foregoing, the essential features, elements and the operationof the device, together with the simplicity thereof, will be clearlyapparent, and when manufactured. in accordance with the invention, aninexpensive market will be easily obtained therefor.

Having thus described the invention, what is claimed as new and usefulby the protec tion of Letters-Patent, is:

' A hand plow comprising a U-shaped memextend at right angles to theU-shaped member having its arms bent at right angles thereber. V 10 toand into a compound curve, four-way In testimony whereof I affix mysignature joint members mounted upon the side arms in presence of twowitnesses.

5'of the said U-shaped member, stub-axles CHARLES S. ERGENBRIGHT.

carried by said four-way joint members, said Witnesses: axles havingwheels journaled thereon "and J. G. PRICE,

disks adjustably carried by the arms which W. F. GLEEOK.
